We can see many kinds of plastic products in our life, like bottle, cap, basket, tube, drum, light cover... and so on. HOW THEY ARE PRODUCED?
They are produced by plastic machinery, like extrusion blow molding machine for hollow products, injection molding machine for injection parts, PET blowing machine for pet bottle, injection blow molding machine for small medical bottle.
Here I will introduce injection molding machine which is for producing injection parts firstly. Injection molding machine is known as an injection press, is a machine for manufacturing plastic products by the injection molding process. Its finished products are widely used in many fields.
Injection moulding machine has two main parts, an injection unit and a clamping unit.
Injection unit consists of three main components:
1. Screw motor drive
2. Reciprocating screw and barrel
3. Heater, thermocouple, ring plunger
Clamping unit consists of three main components:
2. Clamping motor drive
3. Tie bars, the sender is clamped onto the edge of a workbench
The complete production process is like this. First the material is loaded into the hopper. Then enter into the screw and barrel, the solid material melts into molten state by heating. Then molten plastic material enters into the mold and is molded. The finished part is got.
